Simultaneous login oddity

Hi,

I admin a fairly small video post setup ( about 15 clients + XSAN). I’ve come across some odd behavious recently and I am struggling to find any useful tips to solve them.

Basically we run an all 10.4.11 set up with OD managed clients and network homes shared via afp, about 35 users in total. Several times recently I’ve come across users merrily logged in on multiple machines. This is odd because the “allow simultaneous login on managed computers” is definitely off on the accounts where this has occured.

I have also come across odd instances of certain applications that we have disabled in preferences, being available randomly. A login logout normally cures this.

I think the normal procedure in these circumstances is to delete/update cached preference files but I cannot seem to find where the simultaneous login flag lives?

If anyone could point me in the right direction I would appreciate it. What I am seeing is not a show stopper but it is messing with my head and I would like to understand what is coming unglued.

Thanks

Stu
